I am trying to parse command line options using getopts.
for parsing options that are words , for e.g -help, Bash is not allowing me
to do that.
while getopts c:d:fh:help options
do
case $options in
help) echo" Help"
;;
done
The above code does not parse -help option. Any suggestions
I don't think getopts knows how to parse words as options (and not as
non-GNU-style, certainly). You are probably better off writing your own
parser, something like this:
while [ $1 ] ; do
[ ${1:0:1} = '-' ] || break
case ${1:1} in
help) echo help;;
c*)
if [ ${1:1} ] ; then arg=${1:1}
else shift; arg=$1
fi
echo "arg of -c is $arg"
;;
*)
echo "bad option, $1";;
esac
shift
done
